Hello,
I’ve just bought a second hand bizhub c552 with FS 526 finisher.
First, it made disapointing copies – less or more dirty aspect on all - as you can see on pictures 1 and 2 : one thin blanck line on the black and white copy and many grey stripes through the entire color copy.
The seller told me it was an cyan’s Image Unit problem : « The Cyan doesn’t fix »
So I’ve decided to clean it, first by manipulating in and out the cleaning lever, then by using an anti-static and lint-free rag on the accessible section of the photo conductor/C. Finaly, I shaked this drum unit, twice head down and twice head up , before reinstalling it.
Here are the results of this first cleaning on pictures 3 and 4)
As the thickness of the black trails you see seemed to decrease as the copies went on, I continued to gently manipulate the cleaning lever. Here is the result of this second cleaning (picture 5)
You see a line of black drops that crosses the page at the same place that the black trails were located.
Then, a last cleaning with the same rag all around the photo conductor/C by making it turn thanks to the gearwheel gave the result on page 6.
Update : Here the last 4 copies I’ve tried, maybe they’re more significant ; they are all made with mono color mode ( 1st : only K / 2nd : only C / 3rd : only M / 4th : only Y ).
Even if the Cyan doesn’t fix completely ( left side of the copy is a bit wipped ), the Black ink - still on that left side – doesn’t fix at all.
Magenta and Yellow are ok.
Also, on the verso, a black stripe crosses the back.
Can someone here help me ? Have you ideas about where the problem(s) may come from ? or what advices can you give me on how to procede.
Sorry for my english.
Thanks a lot,
Angélique
